|
SiC#32 has been removed from TM2. Quick inspection shows some troubling discoloration on the water cooled connection blocks of C and D as well as the
left target heater A.
As for the target, both legs are broken and is has the normal "charge up" marks on the 9 pin connector. |

Thursday, March 17, 2016, 14:57, David Wang, South Hot-Cell, Repair, TM2, , TM2 first round leak check in SHC
|
Chad and I finished the first round check on Tm2 water lines. The lines and spots checked are: Target oven + and - (front side braze joints) , Tube
heater+and -(front side braze joints and water blocks), coil2 and coil 1(front side braze joints and area close to water blocks),. No leak has been found
on all above of them. The last, we checked the GE which has the biggest leak so far. The leak detector base leak rate only can get |

|
TM2 has been helium pressure tested in ITW and TCS. They are both tested with 70psi helium, each circuit for 3minutes.
The leak detector base leak rate: 0.0X E-9 atm.cc/sec, base pressure 0.0 xE-4 torr for both ITW and TCS. The test results are:

Wednesday, March 23, 2016, 11:32, David Wang, South Hot-Cell, Repair, TM2, , TM2 Helium spray leak check on GE and MSP lines at SHC
|
Chad and I did the helium spray leak check on TM2 GE and MSP water lines at SHC this morning. We confirmed the GE leak on water blocks. We can
not found the MSP leak by using the helium spray since its leak rate in TCS is much smaller than GE leak. The leak check process are as below:

Wednesday, March 30, 2016, 15:49, David Wang, Assembly/Bench Test, Repair, TM2, , TM2 Helium spray leak check on solder stems inside service cap on the top of SW silo. 7x
|
On each water circuit in side the service cap, there are 4 soldering stems which two of them are inside blue nylon insulator and other two are connected
to service tray. Each stem has two soldering spots. See attachment pictures for detail location. I sprayed 15 psi helium on each soldering spots on stems
for 20second on each circuit. I sprayed tons of helium inside each blue nylon.No any leak has been found during the check. The leak detector base leak |

Thursday, April 14, 2016, 07:50: RGA on
Friday, April 15, 2016, 08:09 : Ratio between water and air is higher than normal (indicating possible air leak). See attachment. 3.5 more
H2O than N2. (Ratio in TM3 Nov 2015 was 82:1) |

Monday, April 18, 2016, 09:07, David Wang, Conditioning Station, Repair, TM2, , venting TCS with argon.
|
Anders reported a possible air leak on TM2 and TCS by watching RGA this morning. I found the quick connector on F terminal on the top of the module
is leaking air. It is only used as "X" terminal for Febiad without water. So, it should be blind capped instead of installing a quick connector.
It was installed with a blind cap before. I borrowed it for leak check on coil lines at SHC, but forgot to put it back right away. Instead, I put |
